Generated explanation

Two side-by-side sections illustrate houses supported on pile foundations beneath grade beams. On the left, bearing piles extend through low bearing capacity soil and terminate on bedrock or sound soil below. On the right, friction piles extend into low bearing capacity soil without a depicted bedrock bearing surface. Upward arrows along the friction pile shafts indicate support provided through skin friction. The illustration compares two foundation load-transfer mechanisms rather than correct and incorrect installation.
